Behaviroal momentum

the susceptiblity of responding to disruption by manipulation such as pre-session feeding, deleivery of free food or a change in the scehdule of reinfrocement

consolidation

the establishment of a memory in relatively permanent fomr so that is is availible fro retrieval a long time after orginal acquistion

continouos reinforcement

a schedule of reinforcement in which every occurence of the instrumental resposne produces the reinforcer

discrimination hypothesis

an explanation of the partial reinforcemnt extinciton effect according to which extinceiotn is slower after partial reinfrocment than continouos reinforcement becuase the onset of extinciotn is more difficult to detect following partial reinforcment

exticntion (classical)

reductiion of a leraned response that occurs because the conditioned stimulus is no longer paired with the unconditioned stimulus. Also, the proceudre of repeatedly presenting a coniditoend stimulus without the unconditioned stimulus

extinction (instrumental)

reduction of the instrumental response that occurs becasue the respnse is no longer followed by the reinforcer. Also the proceudre of no longer reinfroceing the instruemntal resposne

forgetting

a reduction of a leraned resposne that occurs becasue of the passage of time, not becasue of particular expereince

frustration

an aversive emotional reaction that results from the unexpected absence of reinfrocment

frustration theory

a theory of the partial reinfrocemnt extinciton effect according to which extinction is retuared after partial reinfrocemnt becase the instruemntal resposne becomes conditioned to the anticipation of frustrative nonreward

intermittent reinforcement

a scheudle of reinfrocement in which only some of the occurends of the insturmental reposne are reinforecd.

overtraining extinction effect

less persisitence of instrumental behavior in extinction folloing extensive traiing with reinforcement than following only moderate levels of reinforcemnt training. The effect is most prominet with continuous reinforcement

magnitude reinforcement extinction effect

less presistence of instrumental behavior in extinction following training with a large reinforcer than following triaing witha small moderate reinforcer

partial reinfroment extincion effect

the term used to describe greater persistence in insturmental respodning in extincion after partial reinforcment training than after continuous reinforcement training

reinstatement

recovery of excitatory responding to an extinguished stimulus produced by exposure to the unconditioend stimulus

renewal

recovery of excitatory responding to an extinguished stimuls produced by a shift away from the contextual cues that were present during extinction

sequential theory

a theory of the partial reinfrocemnt extinciton effect according to which extincion is retared after the partial reinfromcent because the insturemental respsne beocmes conditioend to the memory of non-reward.
